Among Hollywood celebrities, Miranda Lambert and Blake Shelton had one of the quickest and most hushed divorces. Nevertheless, what followed next was an overt display of unresolved baggage from their marriage, ranging from infidelity to throwing their ex spouse's belongings out of the house and so forth.

While "The house that built me" singer picked herself up and gave performances in the following weeks, it seems her ex-husband Blake Shelton has moved on as well. The "Voice" coach is rumoured to be dating singer Gwen Stefani and Miranda Lambert is not happy about it, according to reports.

An insider said, "She's heard about Gwen and Blake and she's really upset. She's always felt like she could never compete with Gwen...This is her worst nightmare," reported Classicalite (via In Touch Weekly).

If rumours are to be believed, Blake and Gwen are quite serious about their relationship, and the "No Doubt" singer has found herself recently single.

Reports of Blake Shelton and Miranda Lambert's relationship surfaced a few days ago when the two appeared to be flirty on and off camera on the set of TV show "The Voice", suggested OK! Magazine.

Gwen Stefani filed for divorce with husband Gavin Rossdale just days after Blake Shelton and Miranda Lambert announced their divorce.
